We don't buy a proven striker due to various reasons because we can't afford one, various proven strikers won't come(Giroud) to a team without European football. English /premier strikers carry a premium. And we have failed to identify one from the lower leagues or the smaller leagues Tosun and Niasse being two examples amongst others. I tend to agree we needed more experience than Kean though who is another project when we needed right here right now this season. I would have had a go for Wilson or Mitrovic at least they are effective at what they do.
